They can be used, for example, for pumping narrow absorption bands in gain media of solid-state and fiber lasers as well as for power scaling by means of dense spectral beam combining.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThis thesis focuses on the analysis and mitigation of the factors limiting the efficiency of high-power distributed feedback (DFB) diode lasers. In particular, it will be shown how a power conversion efficiency in the 60 %-range can be achieved from 10 W-class 100 ¿m stripe DFB-BA lasers ¿ values close to those of state-of-the-art Fabry-Pérot (FP) BA lasers. For the first time world-wide, newly developed DFB-BA lasers achieve 12 W continuous mode optical output power with 62 % peak power conversion efficiency and 58 % at 10 W, respectively. Wavelength stabilization is demonstrated from threshold to 15 A with a spectral width below 0.8 nm containing 95 % of the emitted power. The factors limiting the efficiency of DFB-BA lasers compared to state-of-the-art 10 W-class FP-BA lasers have been identified and as a result largely eliminated.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783954045211\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783954045211","offer_id":39463020101725,"sku":"9783954045211","price":64.98,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/181c2a6a-e680-4794-ba52-bd5996632fc4.jpg?v=1756878832","url":"https:\/\/shop.autorenwelt.de\/en\/products\/analysis-and-mitigation-of-the-factors-limiting-the-efficiency-of-high-power-distributed-feedback-diode-lasers-band-27-von-christoph-matthias-schulz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
